Lake Sfânta Ana
Lake Sfânta Ana (; hu, Szent Anna-tó; ) is the only crater lake in Romania located in the volcanic crater of the volcano named Ciomatu Mare of the Eastern Carpathians, near Tușnad in the Natural Reserve of Mohoș, Harghita County, Romania. Palynology studies concluded that the history of Lake Saint Anne began about 9,800-8,800 years ago, at the stage of peat bog and shallow lake. It has an oval form and an area of 220,000 m². According to measurements made in 2005, the maximum depth of the lake is 6.4 m and the sediment thickness is about 4 m. The lake is supplied exclusively from precipitation, therefore the degree of mineralization of the water is very low. The water purity approaches of that of distilled water, with only 0.0029 ml mineral In winter, the lake is covered with a layer of ice of up to 1 m. The lake is part of the Mohos Nature Reserve. Near the lake there is a Roman Catholic chapel dedicated to Saint Anne According to Christian apocryphal and Islamic tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanic Crater Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ac ...

Volcanic Crater
A volcanic crater is an approximately circular depression in the ground caused by Volcano, volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During Types of volcanic eruptions, volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions, and sometimes of great depth. During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera. Geomorphology In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoe ...

Ciomatu Mare
Ciomadul is a volcano in Romania, and is known as in Hungarian. It is in the Carpathians, close to the towns of Băile Tușnad and Bixad. It is part of a volcanic chain known as the Călimani (Kelemen) – Gurghiu (Görgényi) – Harghita (Hargita) chain and lies at its southeastern end. Ciomadul consists of several lava domes with two embedded explosion craters known as Mohos and St. Ana, the latter of which contains a crater lake, Lake Sfânta Ana. The dominant volcanic rock at Ciomadul is potassium-rich dacite. Volcanic activity at Ciomadul commenced with effusive activity about one million years ago. Most of the volcano was constructed between 650,000 – 500,000 years ago. Between 56,000 and 32,000 years ago explosive volcanic activity occurred at Ciomadul. Both the exact dates of the various eruptions and of the formation of the St. Ana and Mohos craters are unclear, partly because dates obtained by potassium-argon dating and other dating techniques deviate fr ...

Eastern Carpathians
Divisions of the Carpathians are a categorization of the Carpathian mountains system. Below is a detailed overview of the major subdivisions and ranges of the Carpathian Mountains. The Carpathians are a "subsystem" of a bigger Alps-Himalaya System that stretches from western Europe all the way to southern Asia, and are further divided into "Geologic province, provinces" and "subprovinces". The last level of the division, i.e. the actual mountain ranges and basins, is usually classified as "units". The main divisions are shown in the map on the right. To generalize, there are three major provinces (regions): Western Carpathians, Eastern Carpathians, and the Southern Carpathians. Naming conventions The division is largely (with many exceptions) undisputed at the lowest level (except for the Ukraine, Ukrainian part), but various divisions are given for the higher levels, especially for the penultimate level.

Palynology
Palynology is the "study of dust" (from grc-gre, παλύνω, palynō, "strew, sprinkle" and '' -logy'') or of "particles that are strewn". A classic palynologist analyses particulate samples collected from the air, from water, or from deposits including sediments of any age. The condition and identification of those particles, organic and inorganic, give the palynologist clues to the life, environment, and energetic conditions that produced them. The term is commonly used to refer to a subset of the discipline, which is defined as "the study of microscopic objects of macromolecular organic composition (i.e., compounds of carbon, hydrogen, nitrogen and oxygen), not capable of dissolution in hydrochloric or hydrofluoric acids". It is the science that studies contemporary and fossil palynomorphs (paleopalynology), including pollen, spores, orbicules, dinocysts, acritarchs, chitinozoans and scolecodonts, together with particulate organic matter (POM) and kerogen found in sedimen ...

Saint Anne
According to Christian apocryphal and Islamic tradition, Saint Anne was the mother of Mary and the maternal grandmother of Jesus. Mary's mother is not named in the canonical gospels. In writing, Anne's name and that of her husband Joachim come only from New Testament apocrypha, of which the Gospel of James (written perhaps around 150) seems to be the earliest that mentions them. The mother of Mary is mentioned but not named in the Quran. Christian tradition The story is similar to that of Samuel, whose mother Hannah ( he, ''Ḥannāh'' "favour, grace"; etymologically the same name as Anne) had also been childless. The Immaculate Conception was eventually made dogma by the Catholic Church following an increased devotion to Anne in the 12th century. Dedications to Anne in Eastern Christianity occur as early as the 6th century. In the Eastern Orthodox tradition, Anne and Joachim are ascribed the title ''Ancestors of God'', and both the Nativity of Mary and the Presentation of ...

Geography Of Harghita County
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of Romania
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic ...
